CROSS REFERENCE TO RELATED APPLICATIONS

BACKGROUND 1. Field of the Invention

The field of the present invention generally relates to the efficient and durable manufacture, transport, and assembly of a variety of styles of extruded aluminum roof truss for use in building construction as an alternative to factory produced wood trusses. This invention also generally relates to standard component building blocks, such as chords, bracing, connecting pins with locking rings, brackets, and assembly screws, bolts, and nuts, that when used in combination provide a flexible, structurally stable, code compliant and compact alternative to existing wood roof trusses. This invention also generally relates to the reduction in footprint, cost, shipping, assembly, and damage of roof trusses for use in building construction.

2. Description of Related Art

Existing methods and materials for manufacture, transport, and assembly of wood roof trusses for use in building construction are conventional site-constructed stick frame trusses built on site and factory produced engineered wood trusses that have been used in residential and commercial construction projects since the invention of the metal truss plate, such as a gang plate, in the 1950s. Existing truss plates are flat metal plates punched to form a pattern of nail like protrusions on one side. The existing truss plate is installed when pressed into place on a wood beam with the nail like protrusions being forced into the wood to secure joints between wood truss components. Compared to existing conventional site-constructed stick frame trusses, existing engineered wood trusses offer greater quality control, reduced construction time, and lower construction costs although not without significant challenges.

Competitive North American wood truss manufacturers that supply residential and light commercial building projects manufacture existing wood trusses from dimensional lumber in large, dedicated, capital intensive manufacturing facilities. These truss manufacturers design and engineer their trusses to match the plans and specifications for each specific project, then produce the trusses and deliver them to the jobsite. These existing wood trusses are bulky and are shipped as a “truss package” stacked flat on flatbed trucks then typically rolled off upon delivery onto the ground at the jobsite location to be constructed. Shipping costs for the existing bulky wood trusses are a substantial factor in the overall cost of wood truss constructions. Once on site, the existing wood trusses are often lifted atop walls, such as a wood frame wall or masonry wall, with a light crane and fastened to the walls with metal brackets and nails. The process happens on almost every residential and light commercial building project in North America. Existing wood-based roof truss construction is the lifeblood of homebuilders and light commercial contractors as competitive products and materials are generally more expensive and may require specialized training and equipment not familiar with builders and framers.

The existing wood-based trusses tend to be damaged during manufacture, transport, assembly, and installation often requiring additional tasks such as re-design, inspection, replacement, repair, and certification of repairs of the existing wood truss causing delays and added costs.

Residential and commercial existing wood roof trusses are made up of individual wood framing members connected with special metal plates. The wood trusses are strong once installed as a system, however as individual trusses, the wood trusses are fragile and have limited lateral strength or resistance to lateral (wind) loading.

Additionally, safe and successful existing wood truss system installations rely on many variables being correct and are a result of experienced installation crews, attention to detail and safety, proper equipment and bracing, trusses that arrive at the jobsite undamaged, trusses that are dimensionally correct, cooperative weather conditions, and accurate site preparation with bearing walls built so that bearing points on walls match bearing points on trusses. Unsafe and unsuccessful existing wood truss system installations are often attributed to improper or lack of temporary bracing, incorrect unloading and handling, loading or overloading during construction, high winds during erection, weak structural members or bad joint connections; damaged, broken or improperly repaired trusses; or installing unacceptable or unauthorized design changes in the field.

Aspects and applications of the invention presented here are described below in the drawings and detailed description of the invention. Unless specifically noted, it is intended that the words and phrases in the specification and the claims be given their plain, ordinary, and accustomed meaning to those of ordinary skill in the applicable arts. The inventor is fully aware that he can be his own lexicographer if desired. The inventor expressly elects, as his own lexicographers, to use only the plain and ordinary meaning of terms in the specification and claims unless he clearly states otherwise and then further, expressly sets forth the “special” definition of that term and explains how it differs from the plain and ordinary meaning. Absent such clear statements of intent to apply a “special” definition, it is the inventor's intent and desire that the simple, plain and ordinary meaning to the terms be applied to the interpretation of the specification and claims.

The inventor is also aware of the normal precepts of English grammar. Thus, if a noun, term, or phrase is intended to be further characterized, specified, or narrowed in some way, then such noun, term, or phrase will expressly include additional adjectives, descriptive terms, or other modifiers in accordance with the normal precepts of English grammar. Absent the use of such adjectives, descriptive terms, or modifiers, it is the intent that such nouns, terms, or phrases be given their plain, and ordinary English meaning to those skilled in the applicable arts as set forth above.

Further, the inventor is fully informed of the standards and application of the special provisions of 35 U.S.C. § 112(f). Thus, the use of the words “function,” “means” or “step” in the Detailed Description or Description of the Drawings or Claims is not intended to somehow indicate a desire to invoke the special provisions of 35 U.S.C. § 112(f), to define the invention. To the contrary, if the provisions of 35 U.S.C. § 112(f) are sought to be invoked to define the inventions, the claims will specifically and expressly state the exact phrases “means for” or “step for, and will also recite the word “function” (i.e., will state “means for performing the function of [insert function]”), without also reciting in such phrases any structure, material or act in support of the function. Thus, even when the claims recite a “means for performing the function of . . . ” or “step for performing the function of . . . ,” if the claims also recite any structure, material or acts in support of that means or step, or that perform the recited function, then it is the clear intention of the inventor not to invoke the provisions of 35 U.S.C. § 112(f). Moreover, even if the provisions of 35 U.S.C. § 112(f) are invoked to define the claimed inventions, it is intended that the inventions not be limited only to the specific structure, material or acts that are described in the preferred embodiments, but in addition, include any and all structures, materials or acts that perform the claimed function as described in alternative embodiments or forms of the invention, or that are well known present or later-developed, equivalent structures, material or acts for performing the claimed function.

The foregoing and other aspects, features, and advantages will be apparent to those artisans of ordinary skill in the art from the DETAILED DESCRIPTION, DRAWINGS, and CLAIMS.
